Definitions

  • the invention relates to a device for clamping and lifting rammers and a device for holding raised rammers of a ramming machine, in particular for compressing coking coal.
  • the tamper rods provided with friction linings are lifted by eccentric lifting disks, which are rotatably mounted on two opposing, counter-rotating cubic shafts and each part of their circumference bears against the tamper rods and clamps them with each revolution.
  • eccentric lifting disks which are rotatably mounted on two opposing, counter-rotating cubic shafts and each part of their circumference bears against the tamper rods and clamps them with each revolution.
  • Rammers lock the tamper rods in and lift them up.
  • the ramming locks are connected in a rotationally fixed manner. Swing against a fixed stop of the ramming device, so that the bark of the ramming locks are forcibly rotated and the tamper are released.
  • friction linings must be glued to the webs of the tamper rods. This requires a complex, heatable device. Before applying new friction linings, the old friction linings must be sanded down, due to the asbestos content W Coverings, special suction devices and protective measures must be provided.
  • the object of the present invention is to provide a device for lifting rammers and a device for holding raised rammers of a ramming machine which are structurally particularly simple, which reliably avoid sliding friction and which are easy and cost-saving to maintain.
  • a constant lifting height should be ensured over a long operating period.
  • this object is achieved in that an abutment is assigned to each tamper rod, that a first inner surface of the abutment is parallel to the web of the tamper rod, that a second inner surface of the abutment opposite the first inner surface with the web of the tamper rod has a certain, upwardly open angle forms and that between the rammer web and this second inner surface engages a movable clamping body.
  • the proposed device is characterized by a particularly simple construction.
  • the tamper rod is immediately gripped by the clamping body at the beginning of the lifting movement and remains clamped in a self-locking manner during lifting. Sliding friction is thus reliably avoided, regardless of the weight of the tamper. Friction on the webs of the tamper bars is no longer necessary. They are advantageously provided on the surfaces of the abutment and the clamping body which rest against the web of the tamper rod. Since there is no sliding friction, they can be riveted on in a simple manner. The clamping body itself can be replaced without any special effort. Wedges, the wedge shape of which are advantageously provided as clamping bodies.
  • the angle between the tamper rod and the corresponding contact surface of the abutment is adapted.
  • a suitable force generator acts on the element to clamp and loosen the KiemrSystem, whereby the Direction of the force generated is opposite to the direction of movement of the abutment, so that the clamping body is pulled into the wedge seat at the beginning of the lifting movement, while it is released again at the beginning of the downward movement and the tamper rod can fall freely.
  • Such suitable force-generating elements are, for example, hydraulically or pneumatically operating damping systems provided they allow a sufficient lifting height.
  • a hydraulic cylinder is used particularly advantageously, the piston travel of which corresponds at least to the intended lifting height of the abutment. This cylinder is not pressurized, rather the two cylinder chambers are directly connected to a hydraulic tank. The flow resistance of the hydraulic fluid to be displaced counteracts a forced displacement of the piston and thus brings about the force required to put on and loosen the clamping body, which is opposite to the direction of movement of the abutment.
  • the abutment is raised and lowered in a particularly simple manner with a second, controlled cylinder, the cylinder chambers of which are alternately subjected to working pressure.

  • a second, controlled hydraulic cylinder 6 acts on the abutment 2 itself, the two cylinder spaces 6a, 6b being alternately pressurized.
  • the hydraulic cylinder 6 is reversed and the cylinder space 6a is pressurized, so that the cylinder 6 now extends again and the abutment 3 is lowered.
  • the volume to be displaced from the cylinder space 5b of the cylinder 5 prevents the wedge 3 from immediately following the downward movement of the abutment 2, so that the wedge 3 is released and the tamper rod 4 falls freely onto the coal to be compressed. Only when the wedge 3 abuts the stop 9 of the abutment 2 is it forcibly lowered and the piston of the cylinder 5 retracted. The downward movement of the abutment 2 can take place simultaneously with the falling of the tamper rod 4.
  • the abutment 2 is not specifically supported on the frame of the tamper device 1, but is guided directly by the tamper rod 4 itself.
  • the hydraulic cylinder 6 is expediently controlled via a so-called differential circuit.
  • the hydraulic fluid displaced from the cylinder space 6b when the cylinder 6 is extended flows directly into the cylinder space 6a, so that only a differential volume corresponding to the volume of the piston rod has to be conveyed by the hydraulic pump.
  • Friction linings 10 are riveted onto the surfaces of the abutment 2 and the wedge 3 which rest against the web of the tamper rod 4. Any wear of the friction linings 10 is automatically compensated for by wedge 3 being moved up. The position of the clamped wedge 3 relative to a sight mark 11 applied to the abutment 2 allows the friction lining thickness to be monitored in a very simple manner.
  • a tamper lock 12 is assigned to each tamper rod 4 (FIG. 2), which - in a manner not shown - is connected to the frame structure of the tamper device.
  • the rammer lock 12 consists of an abutment 2, and a clamping body 3 guided therein, which in the example shown is designed as a wedge.
  • a first inner surface 7 of the abutment 2 is parallel to the web of the tamper lock 4 and abuts against it, a second inner surface 8 of the abutment 2 opposite the first inner surface 7 is inclined to the web of the tamper rod 4 and forms a wedge seat which is open at the top which the wedge 3 engages.
  • a working cylinder 16 acts on the wedge 3, which in turn is supported on the abutment 2 via a strut 9. By retracting the working cylinder 16, the wedge 3 is pulled out of the wedge seat of the abutment 2 and the tamper rod 4 is thus released.
  • the devices according to the invention are easy to maintain because the wedge 3 is easy to remove.
  • the proposed lifting device also allows a higher stroke frequency of the individual tamper.
  • the rammers can also be arranged very close to each other.
  • the horizontal method of ramming units previously required to cover the entire surface of the coal cake to be compressed can be dispensed with, at least the travel paths required are extremely small.

Abstract

Dans un dispositif de serrage et de levage de pilons ou de maintien en position levee du pilon d'une machine de compactage, les tiges (4) des differents pilons sont retenues par des butees (2) dans des corps de serrage (3) mobiles. Dans le dispositif de levage des pilons, un cylindre de travail, soumis a une commande, agit sur chaque butee (2) pour la lever et l'abaisser. Un autre cylindre (5), non commande, agit sur le corps de serrage (3). Les chambres de ce cylindre communiquent avec un recipient sans pression pour le moyen de travail. Ce cylindre (5) agit par modification du volume des chambres, opposee au mouvement de la butee (2). Au debut du mouvement de levage, le corps de serrage (3) est fermement presse par la butee (2) et la tige du pilon qui lui est liee levee avec elle. Au debut du mouvement de descente de la butee (2), le corps de serrage (3) est libere sous l'effet du cylindre (5) relachant la tige du pilon (4). Dans le dispositif pour maintenir le pilon en position levee, la butee (2) est rigidement reliee au cadre de la machine de compactage pendant que le corps de serrage (3) est presse ou libere par la commande d'un cylindre de pression (16).
